nire res f Maaate MANUFACTURING COMPANY, OF CHCAGO, LLINOIS, CORPORATION F ILLINOIS HOOD LATCH,

Application led March 9,

Vention is to provide such a latch which shallv be simple and cheap to make and etlicient and durable in use. Another object is to provide Y such a latch which shall thrust the edge of the hood inwardly as well as downwardly. i0 Janother object is the manufacture of such a hood latch in which the latch itselfv shall carry a minimum number of projections or extensions. Other objects will appear from time to time in the course of the specilication and claims.

l illustrate any invention more or less diagrammatically in the accompanying drawings, wherein- Figure l is a side elevation of one form of my device; Figure 2 Figure l;

Figure 3 is a section on the line 3-3 01"" Figure 2;

Figures l and 5 are details; Figure 6 is a view similar to Figure 2 or" a variant type; Figure 7 is a partial plan view; y Figure El is a section on the lineS-S of Figure 6;

is a section on the line 2-'2 of ligure 9; and v Figure 1l is a section on the line. ll-ll of Figure l0.

Like parts arev indicated by like symbols throughout the specification and drawings.

Referring lirst to Figures l to 5 A generally indicates the automobile frame member 192s. seria-ino. 260,326.

bei1 A for example bythe bolts'B2. B3 is a central raised portionapertured as at Bt and downwardly depressed about Vsuch aperture as at B5. lt willbe lseen for example from Figure 2 that the top of the'member B3 is downwardly and outwardly inclined.

kSwivelled in the aperture B't is the latch pin'C having at its bottom the head, prefer-- ably a square head C1, which limits it against any substantial arc of rotation by its engage ment with the sides of the base member B. The pin C is headed'at the top as at G2, the upper portion penetrating' the latch cylinder proper C3 with itsl apertured bottom member C4. `Compressed 'betweenthe head of the Apin C2 and the member C4 is a coil springA G5;

which normally tends to thrust the latch cyl# inder C3 downwardly along the pin C. G indicatesa handle member secured .to the top ofthe latch and ,C7 a lateral extension, lug or the'like` preferablybut not necessarilyinte f central aperture D3 of which is transverselyv The upper portion oi" the aperture D3 is of such width as to admit venlargedV as at D4. i

the member C7 oi".l the latch and the members D2 are suthciently widely spaced from the hood VA2 to permitthe 4penetration therebe-` tween of the crosspiece CS..

Slidably mounted'in the enlargement D4 is a member generally indicated as E, shown for example in Figure 5 which includes the central stem E1 which passes through the aperture D4, the' cross piece or head E2 too broad to pass therethrough and the lower en largement or extension E3 downwardly and l outwardly inclined from the stem Eladapted to rest upon the cam member vD.

In, operation the hood latch is manually raised until the cross-piece ltls'clears they tops of the members D2 and is then dropped into y the position in which it is shown in Figure 2. The cross-piece CS theneng'ages thecrosspiece E2 and thrusts the member E downwardly'and outwardly across the cam surface tion of the latch C3 by means of the engaging lower portion E3 of the member E. Sta-ted otherwise, the result, vsince the hood latch C3 cannotV move outwardly away trom'the closure, is thedirection ot pressure inwardly as well as downwardly against the closure A2 and a peculiarly snug lit is insured, with a minimum ot looseiiess orrattlinv.

l7i7hen the hood latch is removed theV meinber cannot be lost since, as clearly shown in Figure ll the sizeof th parts is such that the member E cannot escape from the aperture Dt, having the head E2 at one end of the stem El and the enlargement E3 at the other.

Referring to Figures 6, 7 and 8 a variant form is provided, in which in the place of the cam D and the member E a lever G is mounted upon the closure A2, being pivoted to the outwardly 'projecting bearing Dmeni ber G1. Y

The upper arm of the lever is curved upwardly and inwardly toward the closure A2, as shown at AG2 iii Figuresti and is provided with an enlarged cross piece G3 at its top. The lower armfof the lever is downwardly and outwardly inclined as at G4E and terminates at its bottom in a cross piece G5 adapted to engage the lower portion of the latch cylinder C2.

Extending above` the supporting member .G1 are the two prongs G6 with the aperture G7 between them of sufficient size to admit the projection C7 from the hood latch handle.

' rlhe cross vpieceCS, when the hood latch is in operative position, is interposed between the upper arm G2 of the lever and the prongs GG and theretore tends, in response to the .action of the spring C5, to rotate the lever in countercloclrfwise Jfashion, as shown in Figure 6 and thus todirect pressure outwardly against the lower endl oi' the cylinder C3 and, since the VlatchA cylinder C3.

cylinder C3 cannot move outwardly, to cause a resultant inward pressure against the lower outwardly inclined portion H2 terminating in a re-c'urved end l-l ada ted to eIiO'aOe the .t3 t) n Its lower portion C2 is provided with laterally extending lugs Hk passing through Cam slots H5 in the sides of the member H.v rlShe intermediate portion oi the member H1 is provided with lateral lugs vextending outwardly through gen r H10 from the handle oii the latch. A cross piece ll holds the latch in position once it has ena'ed the knob or. iorlr H9.

ihe operating eilect or the rorin ot Figures 9, l0 and ll is the saine as that of the earlier forms, in that downward pressure directed by the top of the hood latch results inlateral pressure directed against the lower portion ot the hood latch, and thus against the lower goot the closure A2. In the form last described the cam action is provided, instead ot the lever action of the second form.

lt will be realized that whereas l have de- .fcribed a practical and operative device nevertheless many changes might be made in the shane, number and disposition ot 2 L L i, parts without departing irom the spirit oi adapted to direct pressure inwardly against and latch, for translating the downward pres- A sure exerted by the upper portion of'said latch body into inward pressure against said closure, including a member slidably mounted upon said closure.'
